LINER-PLATE FOR CREAM-SEEARATORS.

To all lwhom it may concern Be it known that I, GEORGE L. Runner, a citizen of the United States, residing at La Crosse, in the county of La Crosse and State of Wisconsin, have invented certain new and useful Improvements in Liner- Plates for Cream-Separators, of which the following is a specification. l

The object of my invention is to provide a compound liner plate for cream separa-` tors which will not take up much more room than a Single liner plate and which.

will provide an enlarged passage-way for the cream, thereby facilitating the separation of the cream and its passage from the bowl; and with this and minor objects in view my invention consists in the parts and combination of parts as will be hereinafter more specifically set out.

In the drawing: Figure 1 is a vertical central section through a separator bowl embodying my invention. Fig. 2 is a top plan View of a liner plate embodying my invention. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. 4 is a section on the line 4 1, Fig. 2.

The reference numeral 6-represents a bowl of any approved construction in which I have positioned my improved compoimd liner plates.

7 is the cream exit from the bowl, and 8 the skim milk exit. My improved compound liner plate comprises the outer trun cated cone 9 provided with an annular iiange 10 at its base. 11 is a second truncated cone Vdepending in the Outer cone 10 and supthe inner cone 11 is of less diameter than the` outer cone 9 and is formed on a different angle from the cone 9, said inner cone being held spaced from the outer cone by means of the spacing straps 12. By reason of the diii'erence in angle between the outer cone 9 and the inner cone 11, I provide a cream space or passage in each compound plate of increasing width in the direction of the HOW Specification oflietters Patent.

comparatively restricted space in an opposite direction for the travel of the skimmed `milk, I am enabled to eiiect a better sepa ration of the cream from the milk, inasmuch as the restricted spaces offer a resistance to the passage of the cream through them, thus forcing the cream in the less restricted spaces formed between the inner and outer cones.

`What I claim is:

1. In a centrifugal machine, a series of coaxially arranged liners, each comprising an inner wall and an outer wall inclined in the same general direction to the axis; corresponding walls of the respective liners being spheroidal, 'whereby upwardly enlarging spaces are provided be.- tvveen said last-named walls.

2. In a centrifugal machine, a series of superimposed coaxially arranged liners, each comprising an inner wall and an outer wall inclined in the same general direction to the axis; the inner wall of each liner being spheroidal, whereby upwardly enlarging Spaces are provided between said last-named walls.

3. In a centrifugal machine, a series of superimposed coaxially arranged liners, each comprising an inner wall and an outer wall inclined in the same general direction to the axis; the inner' wall of each liner being spheroidal, whereby upwardly enlarging spaces are provided between said last-named walls, and the outer wall of each liner being frusto-conical.

4. In a centrifugal machine, a series of superimposed coaxially arranged liners, each comprising an inner wall and an outer Wall inclined in substantially the same direction to the axis, but a slightly different angles thereto.

5. In a centrifugal machine, a series of superimposed coaxially arranged liners,

each comprising an inner wall and an outer wall inclined 1n the same general direction to the axis; the inner wall of each liner be- 'ing spheroidal, whereby upwardly enlarging spaces are provided between said fastnamed walls, and the outer wall of each liner being frusto-conical; said inner and outer walls of each liner being radially overlapped.

6. In a. centrifugal machine, a series of superimposed coaXially arranged liners, each comprising an inner wall and an outer wall inclined in the same general direction to the axis; the inner wall of each liner being spheroidal, whereby upwardly enlarging spaces are provided between said lastnamed'walls, and the outer wall of each liner being frusto-conical; said inner and outer walls of each liner being radially overlapped, and each outer wall commencing and ending at a lower level than the comniencing and ending of the inner wall of the same liner plate.

7. In a centrifugal machine, a series of superimposed coaXially arranged liners, each comprising an inner wall and an outer wall inclined in substantially Vthe same direction to the aXis; said inner and outer walls of each liner being radially overlapped, and being provided with circumfer entially narrow connecting bars extending from the lower edge of the inner wall to the upper edge of the outer wall; said connecting bars resting one upon another and spacing the liners in series.
